Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically to a biomass carbonization device. Background Technology

[0002] A biomass carbonization device is a machine that converts biomass materials (such as wood chips, sawdust, agricultural residues, etc.) into biochar, combustible gases, and liquid products through a pyrolysis process under anaerobic or limited oxygen conditions. Based on the principle of pyrolysis, the biomass carbonization device decomposes cellulose, hemicellulose, and lignin in biomass into three types of products by controlling temperature and an oxygen-deficient environment: biochar, a carbon-rich solid residue that can be used for soil improvement, adsorbent materials, or solid fuel; combustible gases, including carbon monoxide, hydrogen, and methane, which can be recovered and utilized as energy; and liquid products, such as wood vinegar and tar, which can be further processed into chemical raw materials or fuels.

[0003] Biomass carbonization devices are widely used in agriculture, where straw and rice husks are carbonized and returned to the field to increase soil organic matter content. In a Chinese utility model patent (publication number CN211871865, titled "A Biomass Carbonization Furnace Feeding Device"), the biomass raw material is thoroughly crushed through longitudinal cutting by a longitudinal crushing roller and transverse cutting by a transverse crushing roller. The crushed material enters the feed pipe through the discharge port and is fed by a screw feeder. In the aforementioned application and existing technologies, feeding is generally done via a screw feeder or direct feeding. However, in the aforementioned application, the biomass is crushed and then fed to the screw feeder by gravity. Since some biomass is relatively light, its weight decreases after crushing, making it difficult for the crushed biomass to directly enter the screw feeder by gravity alone. This results in difficulty in feeding the biomass, segmented feeding, and affects the working efficiency of the biomass carbonization device.

[0004] The methods described in this section are not necessarily methods that had been previously conceived or adopted. Unless otherwise specified, no method described in this section should be assumed to be prior art simply because it is included in this section.
